Why it works: Rice and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,366 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Rice Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Cream the butter in a bowl.
Gradually beat in the sugar and add the lemon juice and rind.
In separate bowls, beat the egg yolks and whites, then combine them with the butter and sugar mixture.
Stir in the rice flour until well combined.
Bake
Pour the batter into a shallow pan, about 2 inches deep.
Bake in a moderate oven at 350°F (175°C) for 35 to 45 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set during baking, and their beaten whites lighten the batter.
- Butter
- Adds fat and tenderness, giving the cake a rich, soft crumb.
- Rice flour
- Forms the main structure of the cake once combined with the eggs and butter.
- Sugar
- Sweetens the cake and helps it brown during baking.
The step that matters
Beating the egg whites separately. Whites beaten to a foam trap air that helps the cake rise and stay light. Folding them in gently, rather than deflating them, keeps that lift in the baked cake.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, rice, flour, egg, butter):

Fit is the average pairing score against sugar, rice, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
